centos7 nginx 开机自启动

参考：

http://www.centoscn.com/CentOS/config/2015/0507/5374.html

 

vi添加nginx.service

[root@klmy-460-res01 ~]# vi /usr/lib/systemd/system/nginx.service

编辑nginx.service内容

[Unit]
Description=nginx
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx      
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop                  
PrivateTmp=true

[Install]
WantedBy=multi-user.target 

 

应用nginx自启动服务：

[root@klmy-460-res01 ~]# systemctl enable nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.

 

开启服务：

[root@klmy-460-res01 ~]# systemctl start nginx
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

有错误，没有开启成功。
